METAL CAP FOR CHIMNEYS.

SPECIFICATION formingpart of 7 Letters Patent No. 234,647, dated November 23, 1880. Application filed August 6, 1880. (No model.)

To all whom it may concern Be it known that I, JAMES BATES, a citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Metal Gaps for Chimneys; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it app'ertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked theren, which form a part of" this specification.

This invention relates to a metal cap for attachment to the top of brick chimneys. The object is to provide a cheap cap made of cast metal, and having such construction as to be readily molded, and that when in position on the chimney part of it will extend down and around the outside and another part down and around the inside and serve to bind the chimney securely together, while provision is made for shedding the water off from the chimney.

In the accompanying drawings, Figure 1 shows a vertical section of the cap as an integral casting. Fig. 2 is a side elevation of same. Fig.3 shows the cap cast in two parts. Fig. 4 is another form of same. Fig. 5 is-the plan or top view.

The letter a designates the inside flange depending from the sloping top I) of the cap. This flange fits within the chimney-top and extends around the inner side, as seen in Figs. 1, 3, and 4. The top 1) preferably slants off, and the sides 0 extend vertically down and around the outside of the brick-work to cover at least two rows of bricks, serving to bind the bricks securely and prevent the chimneytop from splitting from the effects of the weather or from heat and cold. The outer sides, 0, are provided with a flange, d, of any desired width, which slants off and serves to shed the water and throw it from the chimney, thus preventing the unsightly streaks so commonly seen on the sides of chimney-tops.

The lllll'llOVGlllGlll] illustrated in two forms in Figs. 3 and 4 has several advantages. In Fig. 3 the sloping top b and outer sides, 0, are

cast integral, and the inside flange, a, constitutes a separate casting, and is provided around the outer side with a projecting bead, a. By this arrangement the two parts are readily molded, and the top part-,1), with the outer sides, 0, may be set in position on the brickwork, and after being so set the last or the last two top rows of bricks may be added by entering them to their place from the inner side of the top part, I) c, and the finishing up of said upper rows may be done by the bricklayer bet'ore the inside flange, a, is placed in position. Thereby a neat fit is secured of both the inside flange and the outside part, c.

The form shown in Fig. 4 has the sloping top I) cast with the inside flange, a, while the outside part, c, which is separately cast, is provided on the upper edge with an inward flange, c, which rests upon the top row of bricks. The outer edge of the sloping top, in this case, has adown flange, b, which sets around the upper edge of the outside part, c. This form has substantially the same advantages as that shown in Fig. 3.

It will be seen the construction of the herein-described chimney-cap affords all the (lesired advantages, to wit: Being cast metal, it may be produced cheaply and possesses the requisite strength to bind together the chimney-top. It will effectually exclude rain from the upper courses of brick on top, within the chimney-mouth, and around the outside, and will shed or throw off rain-water from the chimney.

Having described my invention, I claim and desire to secure by Letters Patent of the United States- A cast-metal cap for chimneys, consisting of the top part, 1), vertical sides 0, depending from the top part, to extend around the outside of the chimney, a slanting flange, (I, attached to the lower edge of the outer vertical sides, and an inside flange, a, supported by and dependingfrom the top part, to fit within the mouth of the chimney, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAS. BATES.
